APPARATUS FOR MANUFACTURING YARNS 0R THREADS FROM SHORT FIBERS.

SPECIFICATION forming part of Letters Patent No. 747,465, dated December22, 1903.

Application filed September 22, 1903. Serial No. 174,236. (No model.)

To all whom it may concern:

Be it known that I, MAX MijLLER, a subject of-the King of Prussia,German Emperor, and a resident of Altdamm, near Stetti n, in the Kingdomof Prussia,German Empire, have invented certain new and usefulImprovements in Apparatus for Manufacturing Yarns or Threads from ShortFibers, of which the following is an exact specification. My inventionrelates to improvements in apparatus for manufacturing yarns and threadsfrom short fibers, particularly paperpulp, asbestos, and the like, andmore especially to a device by means of which it is attained that thesingle strips of the fibrous material can be wound'up each upon aspecial bobbin or roller and that the whole breadth of the machine canbe utilized for the manufacture of the fiber band.

For manufacturing yarn or threads from short fibers, as paper-pulp andthe like, the small fiber felt bands manufactured upon a paper-machineor in any other convenient way have been brought between rollers movingto and fro in the direction of their axis in order to roll the bands, soas to form a round thread where after these rolled threads were storedup in revolving boxes and afterward brought to the spinning-machine. Inother constructions of machines for the manufacture of yarns and threadsall the fiber felt bands were wound up upon a collecting-roller and wereafterward drawn off from this roller by the spinning-machine. By the useof these collecting-rollers great disadvantages arise, which consist,especially, in the tearing of the single fiber felt bands. In order todo away with these disadvantages, I provide my present invention,according to which no collecting-roller is provided, but each band iswound up separately. The winding up of these bands is efiected byarranging rollers or bobbins, Which move to and fro in the direction oftheir axis, or by arranging suitable guides for the bands, which guidesmove to and fro. In machines in which the single felt bands leaving thesieve are situated, one closely at the side of the other one, the singlebobbins for taking up the bands can naturally not be situated one at theside of the other one on account of these bobbins being broader than thefiber bands, and it is therefore necessary to arrange the bobbins indifierent planes. In the most cases it will be sufficient to arrange thebobbins in four difierent planes for instance, to arrange the bobbinsupon four bars situated in different height, so that the first, fifth,ninth, and so on, bands are rolled up upon the first bar, the second,sixth, tenth, and so on bands upon the second bar, the third, seventh,eleventh upon the third bar, and the fourth, eighth, and twelfth uponthe fourth bar. All the bars or the bobbins situated upon the same mustnaturally move to and fro. By arranging the bobbins in the mannerdescribed above the bobbins can be made much broader, and consequentlythe length of the thread wound upon each bobbin can be augmented,hereby. diminishing the losses during the spinning. By the felt bandsbeing wound up upon separate bobbins a tearing of the bands is avoidedcontrary to the construction of machines in which a collecting-roller isprovided, in which machines the separation of the single bands takesplace after the same leaving the collecting-roller and passing over tothe spinning-machine. The single bobbins can after being filled bedirectly brought to the spinning-machine.

In order to make my invention more clear, I refer to the accompanyingdrawings, in which- Figure 1 is a diagrammatic cross-section of themachine. Fig. 2 is a detail view of the same. i

In the drawings, a is a round sieve of a paper-machine. All detail partsof this machine have been omitted for the sake of clearness.

b is a pulp-reservoir. v

0 represents guide-rollers, and (1 represents bobbins for taking up thesingle bands. These bobbins are arranged upon four bars e e e 6 Thesebars are provided with means for rotating the same and forsimultaneously moving the same to and fro.

The effect of the apparatus is as follows: Upon the round sieve a of thepaper-machine, which round sieve is situated in the pulp-reservoir b,fiber felt strips are manufactured in any convenient well-known way. Thesingle bands pass through the guide-rollers c to the bobbins d, and itwill be seen from Fig. 2 that the first, fifth, ninth, &c., second,sixth, tenth,

&c. the third, seventh, eleventh, 8m. and the fourth, eighth, twelfth,&c., bands are wound up upon bobbins situated upon the same bar.

Having thus fully described the nature of my invention, what I desire tosecure by Letters Patent of the United States is 1. In an apparatus formanufacturing yarns and threads from fibers, the combination of a devicefor manufacturing several fiber felt bands with a separate bobbin foreach band, and means for moving the bobbins or the guides for the bandsto and fro in the direction of the longitudinal axis of the bobbins,substantially as described and for the purpose set forth.
